Crystal structure and spectroscopic properties of the CT complex of methyl viologen dication and o-dimethoxybenzene included in a polycyano - polycadmate host and electrostatic effects on its CT absorption
Article Abstract:
A clathrate including methyl viologen dication (MV(super 2+)) and o-dimethoxybenzene (ODMB) as guests is synthesized using the polycyano-polycadmate host that is a negative-charged Cd cyanide complex with a framework structure built with Cd(super 2+) ions and bridging cyanide ligands. In this clathrate, due to the charge transfer (CT) complex array with the short separation, the effect from the guests overcomes that from the host, and the red shift appears.

Luminescence spectroscopy and visible upconversion properties Er(super 3+) in ZnO nanocrystals
Article Abstract:
Er(super 3+)-doped ZnO nanocrystals with hexagonal wurtizite structure were prepared by addition of LiOH to Zn-O-Er precursors in ethanol. The well known green hot band from the (super 2)H(sub 11/12)->(super 4)I(sub 15/2) transition in the 520 - 540 nm region and Stokes emissions were investigated.

Infrared- and Raman-active phonons of magnetite, maghemite, and hematite: A computer simulation and spectroscopic study
Article Abstract:
Magnetite, maghemite, and hematite are important subjects of numerous studies using vibration spectroscopy to determine their infrared- and Raman-active phonons. However, no complete and unambiguous set of experimentally observed optically active phonons are reported for these iron oxides.
